• Digital to Digital (“dd”) conﬁguration

General

The AMS400A acts as an interface between digital controlling

equipment and a digital control element. It can also provide power for

control elements like valve actuators.

When in automatic mode the AMS400A will adjust the control element

in response to pulses on two digital signal lines from the controlling

device. In manual mode operator adjusts the element and the

“automatic” signals are ignored.

Display

The display provides feedback using the analogue current/voltage

input from the control element or from a suitable measuring device. For

example, if you are controlling a valve, you may want to display the flow

rate.

tatus Outputs

There is a digital ‘status’ output to the controlling device to signal the

operating mode of the AMS400A, i.e., automatic or manual.
